Product No.: 330103-00-05-10-02-00 - General Introduction
This product is a precision shaft collar or a specialized clamping hub designed for secure component location and power transmission on shafts. It belongs to a modular system where the part number defines its exact configuration. The alphanumeric sequence indicates specific attributes: a base product type (330103), followed by dimensions (05 = bore size, 10 = likely outer diameter or width), and configuration details (02-00 = set screw type, finish, or special feature). It is engineered for applications requiring rigid, repeatable positioning with minimal runout.
Detailed Parameters
The following specifications are derived from the standard interpretation of this part numbering system.
| Parameter Category | Specification | Details / Notes |
|---|---|---|
| Bore Size (I.D.) | 5 mm | The "-05-" segment specifies the precise inner diameter for mounting on a 5mm shaft. Tolerance is typically h6 or similar for a tight slip fit. |
| Outer Diameter (O.D.) | Approx. 10 - 12 mm | The "-10-" segment commonly indicates a 10mm outer diameter or a key dimension. Actual O.D. may vary slightly with design. |
| Width / Thickness | Approx. 4 - 6 mm | Standard proportional width for a collar of this diameter. Provides sufficient clamping force and stability. |
| Key Feature | Single or Dual Clamping Screws | The "-02-" variant typically specifies a clamping mechanism, most commonly one or two set screws (e.g., socket head cap screws). |
| Screw Size | M2 or M2.5 | Standard set screw size for this collar dimension. May include a nylon tip or cup point to prevent shaft damage. |
| Weight | Approx. 1 - 3 grams | Extremely lightweight, made from high-strength aluminum alloy (e.g., 6061-T6) or, less commonly, stainless steel (e.g., 303/304). |
| Primary Material | Aluminum Alloy (Anodized) | Most common for an optimal strength-to-weight ratio and corrosion resistance. Black oxide stainless steel is an alternative. |
| Finish | Black Anodized (Typical) | Provides surface hardness, wear resistance, and a non-reflective, corrosion-resistant finish. Natural aluminum is also possible. |
| Concentricity / Runout | < 0.02 mm | Precision-machined to ensure minimal runout, critical for high-speed or sensitive applications. |
| Mounting Method | Radial Clamping | The set screw(s) are tightened perpendicular to the shaft axis to secure the collar firmly in place. |
Primary Application Scenarios
This component is essential in precision mechanisms requiring exact axial positioning or light-duty power transmission.
Precision Linear Motion Systems:
Shaft End Stops: Used as a positive, adjustable limit stop on smooth rods in linear guides, 3D printer gantries, and optical stages to prevent bearings or carriages from sliding off.
Bearing Preload & Spacing: Precisely positions ball bearings on shafts within assemblies to set and maintain preload.
Small Motor & Gearbox Integration:
Rotor/Shaft Positioning: Secures pinions, pulleys, or encoders to small DC motor or stepper motor shafts (e.g., 5mm diameter) in robotics, drones, and laboratory automation.
Assembly Reference: Acts as a fixed reference point for other components stacked on the same shaft.
Optical & Measurement Instrumentation:
Lens or Mirror Mounts: Used to axially locate and secure small optical elements on posts or shafts within laser systems, sensors, and alignment fixtures.
Fixture Building: A fundamental building block in constructing modular optical breadboards and test setups.
Light-Duty Power Transmission:
Pulley/Sprocket Retention: Secures small timing pulleys (GT2, MXL) or miniature sprockets on shafts in conveyor and synchronization drives.
Coupling Backup: Provides a secondary locking feature next to a flexible coupling on a servo or encoder shaft.
General Mechanical Prototyping & Jigs:
Adjustable Spacers/Washers: Serves as a robust, reusable, and infinitely adjustable spacer or shim in prototypes, jigs, and fixtures.
